Free agency kicks off in about a few minutes and there are some relatively big names on the market for the Eagles to pursue.

But a word of caution to those that hope that Birds general manager Howie Roseman will sign cornerback Sean Smith or safety Dashon Goldson or outside linebacker Paul Kruger -- it's not likely to happen.

The Eagles have a host of holes to fill and are expected to target mid-level free agents in attempt to fill those spots and to avoid a bust contract like the one they handed to cornerback Nnamdi Asomugha two years ago.

Case in point: The Eagles released Asomugha this afternoon after two forgetful seasons.

The Eagles have expressed interest in Dolphins tackle Jake Long, according to an NFL source, but landing the four-time Pro Bowler is considered a long shot.

The Eagles have made overtures to the New York Jets about trading for cornerback Darrelle Revis, according to league sources. Whether that means they will be able to bag one of the best defensive players in the NFL remains to be seen.

Roseman would have to give up mutliple drafts picks and would likely have to sign Revis to a contract extension for a transaction to occur.

Free agency begins at 4 p.m., but it will last for several weeks as mid-level veterans visit teams and narrow their choices down. That appears to be where the Eagles are headed.
